OK, I thought this told it to use the ISP's servers if the domain was 
not in the cache.  Are you saying it tells it to use them all the time?

Re your other question, resolv.conf merely lists the IP addresses of 
the ISP's nameservers.

My sense was that resolv.conf was only used for DNS lookups from the 
local machine, which in this case is my firewall.  So having the ISP's 
nameservers listed in resolv.conf will not affect lookups done by 
another machine on the net that connects to the firewall's DNS on port 
53 and goes through named, it only affects those done on the firewall 
itself.  Is that correct?  Or is named also referencing resolv.conf?

Thanks,
